<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">health</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for well-being that I've seen before include "State of being contented" , "State of health or happiness" , "Contentment and good health" , "Comfort, good health" , "Good health and prosperity" .)
